Ferrer, Isner land in Auckland semis

Auckland, New Zealand (SportsNetwork.com) - Four-time champion David Ferrer and former titlist John Isner were among Thursday's quarterfinal winners at the Heineken Open, a final hardcourt Australian Open tune-up.

"It was a very tough match with a lot of rallies and long points," Ferrer said. "But I feel good. I played better than last night and I'm happy because I'm in the semifinals. I played more aggressive, nothing seems like yesterday."
